No they are the gigantic alien and monster and fantasy creature dildos.

Idk, pretty standard for the trades no? I've seen gigantic dildos everywhere from tech backpacks to snap-on roll cabs.

Don't be afraid of a good time!

Thickness matters because the tray table and seat back of the seat in front of you are usually at an acute angle. To get a good viewing angle the screen needs to be open to an obtuse angle. So the top edge of the laptop lid and the seat back will often be in contact to make a comfortable viewing angle, especially if the person in front of you reclines their seat. The thicker the laptop is, the higher the hinge sits. The higher the hinge, the higher the top edge of the lid. The higher that is, the more of an issue this becomes.

Imagine that purple is the tray and seat back, and green is the laptop.

You have options - if the screen is smaller, it'll be less likely to hit. If you slide the laptop out, it gives you more space. That cramps the wrists if you're typing, though, and eventually it'll hit you. Making the laptop thinner gives you more options.

I've not noticed a difference to the battery life in reality but in theory the panel should use a watt less at max brightness (4.1W with the stock N140FGE-EA2 vs 3.1W max on the new one), but also has almost double the brightness so does not need to be ran as high. The main difference is with the colours, the new panel covers 71% of the NTSC colourspace where the other only covers 47%. Plus IPS displays just have much better viewing angles so doesn't need to be viewed straight on.
